  1. Plate Tectonics A Path To Victory!

  2. 1. What is happening here?

  3. Answer 1 Divergent boundary, 2 oceanic plates, mid-ocean ridge forming!

  4. 2. How did these mountains form?

  5. Answer 2 • Folded mountains form when 2 continental plates converge—collide.

  6. 3. How did this most likely form?

  7. Answer 3 Fault block mountains form when continental plates diverge.

  8. 4. What is happening here?

  9. Answer 4 • Rift valley forms when continental plates diverge.

  10. 5. What causes this?

  11. Answer 5 Subduction: When heavier plate dives beneath less dense plate.

  12. 6. What types of plate subduct?

  13. Answer 6 • Oceanic plates subduct beneath continental plates or other oceanic (less dense) plates.

  14. 7. What crustal features form at subduction zones?

  15. Answer 7 • Trench, volcanic mountain

  16. 8. What is forming here?

  17. Answer 8 • Mid-ocean ridge volcano!

  18. 9. What type of boundary is this?

  19. Answer 9 • Divergent: 2 oceanic plates pulling apart.

  20. 10. Where do trenches form? • ??????

  21. Answer 10 • At subduction zones.

  22. 11. What are 2 ways volcanoes can form?

  23. Answer 11 • Mid-ocean ridge Subduction

  24. 12. What powers plate tectonics? ?????

  25. Answer 12 • Convection in the mantle!

  26. 13. Name 3 supports for continental drift

  27. Answer 13

  28. 14. How does subduction form volcanoes? • ???????

  29. Answer 14. • Subducting plate melts then “bubbles up” to form volcano.

  30. 15. How did these possibly form?

  31. Answer 15 • Aleutian Islands

  32. 16. How did this form?

  33. Answer 16. • Two oceanic plates diverging-mid ocean ridge.

  34. 17. What do you think this is?

  35. Answer 17. • Iceland! Part of mid-ocean ridge (Atlantic)

  36. 18. What is this?

  37. Answer 18 • Ring of fire! Subduction zones around the world form this ring.

  38. 19. What happens to rocks as you move away from ridge?

  39. Answer 19. They get older…they move closer to subduction/trench.

  40. 20. What is this showing?

  41. Answer 20. • Rocks formed at ridge record earth’s magnetic field reversal.

  42. 21. What will most likely form at boundary of Antarctic plate and Cocos plate?

  43. Answer 21. It’s 2 oceanics diverging, so mid-ocean ridge.

  44. 22. What is causing the Himalayas to form?

  45. Answer 22. 2 continental plates converging.

  46. 23. Where is oceanic crust destroyed? ??????

  47. Answer 23 • Subduction zones!

  48. 24. Upwelling here shows what forming?

  49. Answer 24. • New ocean floor/rock

  50. 25. Where in the U.S. would we find a transform boudary? • ?????
